Dedicated power


I'm looking to run a dedicated 30a and dedicated 20a line to my system directly from the fuse box. 
I currently have some florescent lights and some other junk on the line so I'm hoping it will be an improvement. Things sounds like they are straining somewhat when you crank things up. The amp will go on the 30a line and the digital stuff on the 20a. 
Anyone done this and saw improvements?

I’d have to say that the big difference is probably that in the U.S., the flooding very often comes hand in hand with some very serious storms. These would be the occasions that people might be without power for extended periods ... Most (all?) of the events with extended outages in the U.S. have been the result of horrific storms, hurricanes, or tornadoes with winds in the 130-200mph range, and often rainfall measured in feet.
Nope. I live in an area not especially subject to those conditions and when we lose power it’s not uncommon for the outage to last for two weeks. (To be fair, sometimes it's "only" for two or three days.) The poles and equipment that feed my neighborhood - which has underground service - often date to the mid-40s, according to the crews who repair the work. When repairs are made, the replacement poles and other equipment is to the same spec as the equipment that failed, so it’s sure to fail again. If the electric utility does upgrades in my state, it’s never in my neighborhood. State regulators make promises but can’t show results.

My electric utility also suffers from other performance problems, but that’s a bit OT. Many of my neighbors and I consider our electric service to be of third world quality and these power problems have resulted in deaths more than once. It’s pathetic.
I was talking to some linemen, when a transformer blew on my street, they said it isn't uncommon for the transformers to be run at 200% capacity.
Well finally had the dedicated lines installed. I have to say it sounds denser and cleaner. Better bass definition and whatever little bit of hash in the highs seemed to be diminished. Everything seems tighter and better separated. Obviously this is not a blind test and yes there was/is some bias of wanting to hear an improvement. I have been working out of this room for a year so I listen basically all day long if not on a meeting so I have a pretty good handle on the difference. All I know is it did no harm and I feel like there is a noticeable improvement. I would highly recommend doing this if you don't need to rip a bunch of drywall up for the small investment. A fraction of what some power cords cost.
Update. This is for sure real. Before the dedicated lines there was a hiss with nothing playing. Not bad at all but could hear from maybe 6 inches to a ft away. Now dead silent. Nothing.
